Abstract :

Network concepts have been widely applied in structure biology research to help the understanding of protein structure and function. Our research approach is based on applying small world network concepts to ligand-protein complexes, using atomic level representation of favorable close contacts, focusing on local cooperativity. Specifically, we believe that there are patterns of networked interactions, currently overlooked using traditional additive methods that play important roles in ligand-protein binding. We believe small world network concepts are keys in identifying these patterns because although they may involve weakly favorable contacts, they can be highly stabilizing. To demonstrate the effectiveness of these novel small world network concepts we show complexes involving Aurora A kinase, and how the visualization of key interaction networks supports the rationalization of binding site hot-spots and residue mobility. To further explore the local cooperativity of interacting residues in protein crystal structure data, we introduce new and novel methods for the fast searching of networked interactions.
